Be it ,known that I, YANA-BUI-:'EN ALLEN., a citizen ol the United States, residing at Brooklyn, in the county of Kings', State of New York, have made a certain new and thev following is a specification. y

This invention relates to lock mechanism which 1s adapted to be applied to a. door, or

useful Invention in Prison Locks, "Of which to each oi a series, or tiers,of doors, gates and the like, and is so constriiicted and ar- .ranged that it may be operated by 'an attendant stationed at `seine jdistance trern lthe door, oir doors, to which the mechanism is f fapphed, and which may "be operated by commonoperating lever or means.

The object of my invention includes the .making of a lockmechanism which Vis strong, Vcheapand simple in constructiomyet and effective in operation, and which is practically proof ,against tampering, or. renderlng inoperative by unauthorized persons It is my further .object .fto provide `a ymul- .tipleofyboltingor :locking devices for .each

l .door or gate, and yto so` apply, locate and protect the :same as `to make it impossible to :open said door when t-he .same is locked. l .have further provided a `construction and .means whereby said b'olting and lockingdevices may L ybe :simultaneously 'operated either fortlockingfor foriu-nlocking said door,

or tier ofdoors, or gates, or forleaving individual `doors or ygates-1n said tierflocked.

when the operating lever is moved to the left, for example, the shoes will tilt rorward, and toe 37 will depress `the plunger bar 33 to operate' the lock in the manner mor'e fully described below. At the same time the `foot of said shoe, and foot 4J o shoe d4; will be moved downward to thereby bolt the door vor equivalent structure, as is clearly illustrated in Fig. l. Lock lever 28 has an extension lr-8 for engagii'ig lug 49, and leg 22, of the boltl operating member, is of suiiicient length to catch unvder lug 50, when the lock lever is depressed.

gaging position at 49, and will also by depressing plunger 30 move the bolt` operating member intoV operative position in the following manner. As the bolt operating member turns on pivot 20, the leg extension 22 moves into lug engaging position at 50, and head 28 moving on its pivot at 20, engages the pin head L17 to throw the main lock bolt into locking position. The head 23 serves also the important 'function of Vcovering the key hole while in this position, as is clearlyv shown in Fig. 2. In the door is bolted and secured at five different points, namely, at the upper part where the two shoes contact, at the side where lock lever 28 and leg 22engage their respective lugs, and also where themain bolt 11 slides home. In this position the trigger' linger positively locks the bolt against retraction by engagingv with guide lug 12. In unlocking this vtorm of lock,it is necessary to employ a proper key for lifting the trigger linger which key then slides the bolt back. This can be however, only after the head of the bolt operating member has been moved back to unlocked position. y

From vthe above description, it is apparent that when the bolt operating member is in locking position` the key hole is securely covered, therebyv defeating any attempt to tamper with the lock while the key hole is uncoveredwhen the door is unlocked or when it is open. lIt is further ob'- vious that I could readily provide a simple slide 60 and operated by a cam 61 to proc main bolt.

`whereby said main bolt is moved.

In Fig. 7 I have shown a modication ot my bolt operating member which will vob,n viate the use of a `key 'for throwingl the IrIere the bolt operating member is operatively connected to the main bolt Il by a suitable connection which is diagrammatically illustrated at 52 for sliding the finger may in this type of. lock be omitted,

if desired.

From the above description, it is'apparent a tier or doors in any desired number may be locked or unlocked vtroni. a pointremote from the doors by the simple movement oi the operating lever, which obviously may be of any desired length necessary to operate all the door locks-in a particular tier.` obvious that by my invention all of the doors may be simultaneously locked, and the several auxiliary bolts may be as simultaneously bolt back and forth and the trigger It isy unlocked, but the main boltmay be leftV in a locked position, to be thereafter unlocked by a key or equivalent device. 'This may be desirable under certainconditions, but ordinarily all the doors will be locked and unlocked simultaneously by an attendant moving the operating lever.

While I have shown and described specilic construction illustrative of my invention, I do not thereby desire to be understood as having thus limited myself, as obviously various modifications coming within the gest themselves to those versed in the art. What I claim, therefore, as new and useful Aand of my own invention and desire tohave protected by Letters Patent is:
